Patent GB-565430-A (GB)
Title: Improvements in and relating to controlling automatically the speed of dynamo electric machines
IPC: H02P23/00
Filed: 1941-12-24
Abstract: 565,430. Automatic control systems for dynamo-electric machines. SMALL ELECTRIC MOTORS, Ltd., ADORJAN, P., NASH, J. E., and ROGERS, E. W. Dec. 24, 1941, No. 16640. [Class 38 (iv)] Speed.-The speed of a dynamo-electric generator subject to considerable load variation is controlled by supplying a fluctuating component of the generated voltage after amplitude levelling to a circuit resonant to the frequency of the fluctuation. A generator 4 of supersonic A.C. voltage is connected through a resistance 10 and an isolating condenser 9 to a parallel circuit containing a tapped inductance 12 and condensers 14. A discharge tube 8 eliminates the amplitude variations in the voltage applied to the resonant circuit. At a speed giving a frequency slightly below that to which the circuit is tuned by selective operation of ganged switches 13, 15, the excitation of a winding 23 in the output circuit of a pentode valve 20 gives stable operation, but speed variations in either sense cause corrective changes in the excitation due to changes in the rectified voltage applied to the grid of the pentode. The winding may be an auxiliary field winding of a D.C. motor 5 or may control the throttle 29 of a prime mover driving the alternator. To prevent excessive speed at starting, while the pentode is warming up, a similar control circuit responsive to, a higher frequency of the alternator may operate a relay 41 to energize a second relay 43 which gives the winding 23 a predetermined excitation and reduces the screen voltage of the pentode. The speed then falls below that to which the circuit 31, 33 responds and the action is repeated until the valve 20 produces the current required to hold the correct speed. In a modification, the pentode output operates a relay when warmed up. This relay then disconnects the winding 23 from a fixed excitation supply and connects it to the pentode, at the same time making its own retaining circuit and reducing the automatic grid bias due to an anode resistance such as 22. In this modification, the circuit is responsive at a frequency slightly greater than that of resonance and the winding 23 opposes the normal motor field. In a further modification, according to the Provisional Specification, the valve may control the supply of power to the motor.

Title: An arrangement for ascertaining the departure from synchronism of two correlated impulses
IPC: G01R25/00
Filed: 1955-06-10
Abstract: 796,787. Automatic registration control systems. LICENTIA PATENT - VERWALTUNGS-GES. June 10, 1955 [June 11, 1964], No. 16707/55. Addition to 756,009. Class 38 (4). [Also in Group XL (c)] In registration control of multi-colour printing-machines short, positive, impulses derived by photo-electric scanning of two printed marks of different colours (or one of them produced by a contacting device rotating synchronously with the machine) are applied to grids of two normally non-conductive vacuum tubes 1, 2 having pulse-widening circuits 10, 11 at their inputs so that the flow of both anode currents operates a relay 6, 7 to disconnect the H.T. source before the first widened pulse ceases. A voltage thus develops across a capacitor 5 shunting equal anode resistors 3, 4 during the time interval before the presence of both pulses and the time integral of this is indicated by a meter 17 as a measure of the phase or time between the instants of commencement of the pulses. Rectifiers 18 prevent discharge of the capacitor 5 through the resistors 3, 4 after HT + is disconnected. Alternatively the input pulse widening circuits may be at the anodes of the valves, or the inputs to the grids may be wide pulses. The valves may be pentodes acting as limiters and with D.C. regenerative feedback between-their anode current outputs and control voltages produced by magnetic amplifiers to shorten the pulse build-up times.
Patent GB-757800-A (GB)
Title: High molecular weight phosphorus containing anti-enzymatic substances and a method for the production thereof
IPC: C08G79/04
Filed: 1953-06-17
Abstract: Polyphosphates or -thiophosphates having a molecular weight of at least 2000, but being still soluble in water or alkali are formed by condensing phosphorus oxychloride, thiophosphoryl chloride or one of those substances together with phenoxyphosphoryl dichloride, with a glycoside of the flavone, flavanone, or corresponding chalcone or dihydrochalcone series which contains at least two free phenolic hydroxyl groups.  The condensation products are hydrolized to remove surplus acid chloride groups and to effect depolymerization to a suitable molecular weight, if necessary.  Suitable glycosides are phloridzin, dihydronaringinchalcone, naringin, hesperidin and rutin. Suitable aglycones and saccharides are also listed. Hesperidin is said to give products of lower stability.  The products have anti-enzymatic activity especially against hyaluronidase.  In addition to the structural phosphoric acid residues the compounds may contain acid phosphate or sulphate groups attached to extra phenolic hydroxyl groups or more particularly in the saccharide part.  A tertiary amine is preferably used as a hydrogen halide binding agent during the condensation.  It may also act as a solvent or a separate solvent, e.g. ether, dioxane or acetone, may be employed.  If desired the phosphorylation mixture is cooled, and the phosphorylating agent added slowly or in stages.  The glycoside and phosphorylating agent may be mixed and the reaction started by gradual addition of condensing agent.  The products are obtained by evaporation to dryness, if desired after dialysis.  Further purification may be effected by alternately dissolving in alkali and precipitating with acid saturated with common salt and, if desired, ethanol.  Examples (1)-(5) describe condensation of phloridzin with phosphorus oxychloride in pyridine followed by hydrolysis with crushed ice. Example (6) also employs some chlorsulphonic acid.  Examples (7)-(10) start with dihydronaringin chalcone.  Example (11) uses naringin. Examples (12), (13) start with hesperidin and Examples (14)-(17) with rutin.  Examples (18), (19) illustrate the use of thiophorphoryl chloride and Examples (20), (21) condensations in dioxane without a hydrogen chloride binding agent.  The power of the products of inhibiting hyaluronidose is measured and expressed in a manner which is described.  Specification 700,761, [Group IV (b)], is referred to.
